Hi, good day everyone.

I just bought myself a used i5-3470 and a rx480 since im not ready for a full platform upgrade and i already have a h61 mobo and ddr3 ram. I was checking the temp im getting with the cpu and noticed that the cpu gets more than 80 degrees, on full load. Im using the stock intel heatsink(the one with copper in the middle). Got this new from a friend of mine.

I thought i might have installed things wrongly.. So what i did was, cleaned the old thermal paste, installed fresh paste, and installed back the heatsink. Tried, and yet the thermals were high.

This time i took everything out of the case, went through the same process of installing new thermal paste and checked the thermal with full load. Even after 6 mins of full load, the thermals were below 80, hovering around 76-79, whereas earlier it would go above 80 degrees in just few minutes.

Installed everything back in the case as they were and checked the thermals back and it goes above 80 degrees back again. Im clueless now. Im not sure if a case can make such a drastic change in thermals. You guys have any ideas as what I should do now?

1) Im not sure if the heatsink moved or anything like that after i tried on the table while installing it back in the case. I guess it shouldnt move or anything like that since the heatsink is tightly locked to the mobo.

2) I used a different psu while trying on the table? I highly doubt that the psu is the culprit.

3) I didnt install the graphics card while trying the mobo and cpu outside of the case. The graphics card was installed when i was checking the temp of cpu when its all in the case. Again, I doubt that the graphics card is the culprit.

Hope someone could shine a light on how to tackle this situation. Thank you in advance.

Likely your case is a little restrictive but the main issue is the weak cooler. I would get a hyper 212 evo on the budget end, cryorig h7, or dark rock pro 4

Owh okay. But isnt the stock cooler supposed to keep the temperature below 80?

BTW, if let's say I get the hyper 212, the thermal issue could be definitely solved right? Cause I'm worried if the issue is not solved even after getting an aftermarket cooler.

The stock coolers are designed to be as cheap as possible while keeping the processor under thermal throttling which is about 100c. The hyper212 should solve this issue buy brining the temps down a bit. A better cooler like the cryorig or dark rock would work even better but even the hyper 212 is leagues above the intel stock cooler.

s03,

The cooler you've described is Intel's universal 95 Watt TDP cooler, which is the cooler specified (2011D) for the 77 Watt TDP i5 3470: Intel® Core™ i5-3470 Processor - https://ark.intel.com/products/68316/Intel-Core-i5-3470-Processor-6M-Cache-up-to-3-60-GHz-

It's normal for Core temperatures bench tested outside a case, compared to inside a case with covers installed, to vary with case quality, airflow and components such as fans and graphics cards. If temperatures differ more than a few degrees between open bench and closed case, then case ventilation and cable management should be addressed.

Throttle temperature (Tj Max) for your i5 3470 is 105°C. However, since we know that cooler is better for ultimate stability, performance and longevity, it's prudent to observe a reasonable thermal margin below Tj Max.

As such, here's the nominal operating range for Core temperature:

Core temperatures above 85°C are not recommended.

Core temperatures below 80°C are ideal.

Core temperatures increase and decrease with ambient temperature. The accepted "standard" for normal room temperature is 22°C or 72°F.

When attempting to compare apples to apples, Core temperatures are also highly dependent upon two other critical variables that weren't mentioned in your explanation:

(1) What was your ambient (room) temperature?
(2) What did you use for "full load"?

I was thinking something like why should i spent more for an older gen processor, hoping that i could make use of the stock cooler. Hyper 212 is not something thats really cheap in my country though.

Try this. It is a relatively budget cooler but it demolishes stock coolers.https://www.newegg.com/Product/Product.aspx?Item=9SIA68V4H84953&ignorebbr=1&source=region&nm_mc=KNC-GoogleMKP-PC&cm_mmc=KNC-GoogleMKP-PC-_-pla-be+quiet%21-_-CPU+Cooling-_-9SIA68V4H84953&gclid=Cj0KCQiAtP_iBRDGARIsAEWJA8jPZb1aYChYIWV_48x1Lx3vZbUaeVQQsHKbf8AlMVbcalpuNkT8OTkaAofdEALw_wcB&gclsrc=aw.ds

1)26 degrees
2)cpu-z stress test

I just used prime 95 small fft test and within minutes the temperature went up to 89 degrees and i quit the test. Do you feel im in a state where aftermarket cooling is a must? Thanks.

Hyper 212 is more cheaper in my country. Haha. Thanks btw.

No. Your stock cooler should be adequate. Keep in mind that 26°C is 4°C above the standard which is 22°C for normal room temperature. This means "normalized" Core temperatures would be 4°C lower in a normal environment.

Further, the stress test in CPU-Z is not "full load"; it's only about 80% workload. Utilities that don't overload or underload your processor will give you a valid thermal baseline. Here’s a comparison of utilities grouped as thermal and stability tests according to % of TDP (Thermal Design Power), averaged across six processor Generations at stock settings rounded to the nearest 5%:

All tests will show 100% CPU Utilization in Windows Task Manager, which indicates processor resource activity, not % TDP workload. Core temperatures respond directly to Power dissipation (Watts), which is driven by workload. Prime95 v26.6 Small FFT’s provides a true and steady 100% workload.

If you ran a version of Prime95 later than 26.6 such as 27.7 through 29.4, Core temperatures can be up to 6°C higher on 2nd and 3rd Generation processors due to "AVX" Instructions Sets, and up to 20°C higher on 4th Generation and later due to "AVX2" Instruction Sets. Give it another try with the proper version and let's see what you get:

• Prime95 v26.6 - http://www.mersenneforum.org/showthread.php?t=15504

Realistically, the only instances in which users run "stress" test utilities is to check stability or thermal performance. Even if your computer is in a normally hot environment without A/C, if you don't run any heavy apps that approach 100% workload, and Core temperatures don't routinely run above 85°C, then your stock cooler should still be adequate for a non-overclockable processor.

Yeah my computer is normally in a hot environment without A/C. I just ran small fft test with Prime95 26.6 and I quit the test just in few minutes cause the temp hit 100 degrees. I used CPUID Hwmonitor to monitor the temp and was checking the package temperature. The ambient temperature currently is 33degrees. Do you i feel i should continue to run the test longer?

No. If your cpu is around 100c it could start to throttle and get damaged. I would buy a better cooler ASAP. You are unlikely to see that temps in games though. My cpu after an overclock runs mid 70s in 26.6 prime 95 but can spike to 80s after a while. It runs high 60s-low 70s in games.

I've never used any aftermarket cooling before, so im not sure about the clearance issues. I have an ASRock h61m-vs3 mobo and hyperx fury ddr3 ram. Will i have any clearance issue such as the heatsink having contact with the ram and so on? My case manufacturer website states that the chassis dimension is 405 x 185 x 446mm. Do you feel im gonna be fine with the hyper 212 turbo? What else do i need to take into account?

Appreciate it, really. This cooler is shipped from overseas and i dont usually buy products from overseas since it takes some time to reach, and i never had a good experience before. Not sure about sending for warranty and stuffs too. So i always buy products that are shipped locally. I can get hyper 212 for the same price as this locally through the same site. Guess that should be fine too.
